Anyone's boy but "Mama's Boy"

This breaks my heart to post. Part of me feels it can be my pregnancy hormones at a peak but it has been for quite a few weeks. Please be gentle in your responses.

My little boy is a year old and I am pregnant with our second baby, due in January. I am home on summer break with him but I feel as though he could care less. I have kept our routine of naps and meals, but have mixed in some fun of visiting places, taking walks, and going to the pool. We constantly play, talk and interact but I feel as though it's not enough.

Even with these, it feels as though whenever his father, grandmothers, or even the mailman (being dramatic but it sure feels this way) appear, his hands go up and he immediately wants the other person. If I am away and I appear, he will look at me then continue his play. He will reach out for others while I hold him and will not let me hold/rock him unless I nurse him (which has cut back due to supply and I have cut back to only at night, of at all).

My mother was just holding him on a recliner as he laid sweetly on her, something I've never been able to do. While doing family pictures with a photographer and holding him, he continued reaching for my mother-in-law.

I am just at a loss for words. Is it too much or too selfish to say I want my baby to want me?
